CHURN Filed April 24'. 1929 Patented June 24, 1930 UNTEB STATES yeAnnIs D. wieeins, or LA FERIA, TEXAS CHRN Application filed April 24,

rihis invention relates to churns and similar machines and has for its object the provision'of a structure which will firmly support the dasher shaft when it is in use and will permit it to be quickly removed from the container when the churning or other operation has been` completed. The invention is illustrated in the accompanying drawing and will be khereinafter fully set forth.

In the drawing:

Figure 1 is a front elevation of a churn embodying the invention,

Fig. 2 is a vertical. section on the line 2-2 of Fig. 1, and

Fig. 3 is a detail horizontal section on the line 3 3 of Fig. 2.

' In carrying out the present invention, there is provided a pair of standards l1 which have their lower portions forked and diverge to form legs 2 whereby they may be firmly supported upon any convenient base. The Lipper extremities of the standards are connected by a cross bar 3 and a similar cross bar 4 is secured to and extends between the standards at a point below the top, as clearly shown in Fig. 2. The front edges of the cross bars 3 and 4 are formed centrally with semicircular notches 5 to accommodate the dasher shafts or rods and mating with said recesses and cross bars are bars 6 of a gate or swinging head which is hingedly connected to one of the standards and is adapted to extend across the front of the frame and be releasably secured to the other standard. The cross bars 6 of the gate are connected vertically by stiles 7 and midway the ends of the stiles a cross bar 8 is secured thereto, said bar furnishing a bearing for a stud shaft 9 carrying a main driving gear 10, as shown. The cross bars 6 are formed with semi-circular notches or recesses 11 which mate with the recesses 5 in the cross bars 3 and 4, as shownV in Fig. 3, and the stile 7 more remote from the hinges 12 is equipped with any preferred form of latch whereby the gate may be fastened to the frame about the dasher shafts or rods. n the present drawing, the latches are illustrated as set bolts and wing nuts, indicated at 1929; Seria1No. 357,814.

13, but anyeiicientlatch may be employed. A container 14 is disposed between the lower portions of the standards and a split topl is fitted inl the top of thecontainer.` This top lor cover consists of two -semi'circu' lar members secured together by a hinge 16 and provided in theirstraight meeting edges with recesses adapted to fit around the dasher rods, as will be understood. They are also constructed with an external annular shoulder 17 whereby they may fit withinthe top ofthe container and rest on the edge of the same, as ywill be understood upon reference to Fig. 2. -Two dashers or sets of dashers` are employed, the lower dashers 18 being carried by a hub 19 which is secured to the lower end of an inner dasher shaft or rod 20 by a set screw 21, as clearly shown in Fig. 2.. .This inner dasher rod or shaft extends upwardly to a point immediately below the top cross bar 3 of the frame where it is. equipped with a spur gear 22 meshing with the driving gear 10 and, above the gearthev end of the shaft is enlarged to form a pintle 23 rotatably fitting in lthe alined recesses 5 75 and 11 of the cross bars 3 and 6 and* formed with an expanded head 24 above y'the cross barsland with an annular shoulder25 below the cross barsv whereby the head and the shoulder will hold the dasher rod or shaft against vertical endwise movement and, consequently, maintain the engagement of the gears 10 and 22. The upper dashers 26 are secured to the lower end of an outer hollow shaft 27 which fits around the shaft or rod 20l and-is formed or provided at its upper end with an annular flange 28 bearing againstthe under side of thefcross bars 4 and 6 and'equipped at its upper extremity with` a gear-29 meshing with the gear l0, as shown, an annular shoulder, indicated at 30, beingformed upon lthe rod or the gear to rest on the upper sides of the mating bars v4 and 6 so that said bars will closely encircle the Lipper end of thevdasher rod or shaft and prevent vertical endwise movement thereof. It will, of course, be noted thatthe'gear 22 meshes with the gear 10 at the topk of the sameand the gear 29'meshes with the gear 10 aty the bottom ofthe same so that, when rotation is imparted to the driving gear, the dasher rods or shafts with the dashers thereon will be rotated in opposite directions. The driving gear 10 is shown as equipped with a handle() for hand operation, but it will be understood, of course, that the device may be driven from any source of power. The dashers each consists of a hub or collar secured to the corresponding shaft or sleeve and a blade extending radially from the hub and disposed obliquely with respect toits vertical extent.

From the foregoing description, taken in connection with the accompanying drawing, it will be seen that I have provided an eX- ceedingly simple and inexpensive structure whereby the dashers will be firmly held in their proper operative positions when the churn is in use but may be readily removed 1 when the churning'operation has been completed. By releasing the latches 18 the gate or closure may be swung laterally about its hinge connection with the frame and this swinging movement will carry the driving ,v gear away from the driven gears and leave the dasher rods or shafts accessible from the front of the apparatus. If the container 14 be now slid forwardly, the dasher rods will, of course, be moved out of the recesses in which they were fitted and the cover 15 may then be lifted from the container and opened so as to be released from the dasher shafts, whereupon the dashers may be lifted from the container. A reverse operation will assemble the parts in operative relation eX- peditiously.

Having thus described the invention, I claim:

A churn including a frame comprising standards, upper and lower cross bars eX- tending between the upper ends of the standards andsecured thereto, a gate hinged to one standard and adapted to be releasably fastened to the other standard, said gate having upper and lower cross bars bearing against the upper and lower cross bars carried by the standards and` an intermediate cross bar, the upper and lower cross bars of the gate and standards having their contacting side faces formed with registering recesses constituting bearings, concentric shafts received in the recesses of the cross bars and rotatable therein when the gate is closed and readily removable when the gate is opened, gears fast upon the respective shafts, a driving gear rotatably connected with the intermediate cross bar of the gate and movable therewith into and out of engagement with the gears fast upon the two mentioned shafts, a receptacle receiving the lower portions of said shafts, and beaters carried by said shafts for operating in the receptacle.

In testimony whereof I aiix my signature.
